Most of the profiles you will see in your Beeline are not fake. They are real profiles that liked you, Bumble bot detection is pretty good. However, Bumble will sometimes claim when you are not a Bumble Boost subscriber yet, that there are more than 1000 people that already liked you.

Why does my beeline decrease?

This means your age and distance preferences and any Advanced Filters that you have set will filter out users in your Beeline. All you have to do is relax those filters (don't worry -- you can reapply them at any point) and your Admirers will appear in your Beeline again.

What does it mean when people are in your beeline on Bumble?

The Beeline is a list of profiles who have swiped right on you but you haven't swiped right on yet. This obviously makes it easier to find a match. To view the potential matches on your Beeline, you have to upgrade to Bumble Premium, which you can do on a weekly basis or for longer subscription periods.
